The lack of LTE compatibility in Australia is due to the historical set of frequencies that the carriers (mainly, Telstra) are using here for it. It's well known to anyone who pays attention to these things in Australia. It's interesting they ship the same model though.

The model numbers on the back of the 9.7 inch LCD lead us to believe this is a Samsung LCD.

Beside the numbers we find three mysterious matrix barcodes. They allure the teardown expert, a dubious distraction indeed. What do they do? Our best guess: crash your iPhone or turn it into an iPad...scan at your own risk.

The PDF linked from Step 11 of this links to a display with the designation LTN097XL01-A01, not the LTN097QL01-A02 listed on this page. Could be a variant, but the tech info also lists the resolution as "1024 x 768 pixels".

FM transceiver? Is this being utilized by something not obvious? Or is this just an artifact of an off-the shelf chip. It would be amazing if developers could write FM transmitter apps (for broadcasting to a car stereo like external devices can do). Or maybe receive FM transmissions and use a 'Radio Tuner' app.

If I'm making it out right, the Elpida RAM has a -8D marking making it LPDDR2-800. That means RAM speed/bandwidth is unchanged from the Apple A5 which is disappointing considering the greater need to feed the GPU.

As is the case with most tablets, the iPad 3 is really just a giant battery.

Some help from our spudger allows us to remove the battery from the device for further inspection.

While the iPad 2 housed a formidable 25 watt-hour Li-ion battery, the iPad 3 has upped the ante to the tune of 42.5 watt-hours.

Its 3.7 volts and estimated 10 hours of use (9 with cellular data network) are comparable to that of the iPad 2, but we assume the extra 17.5 watt-hours are put to good use powering the extra RAM and greatly improved GPU.

I'm really interested in the physical size difference between the iPad 2 and this battery. Mostly the weight. Is this some new battery "tech" or is it the same technology just more battery material? Since it is almost double the capacity 42 watt-hours versus 25 of the iPad 2.

I'd also be interested in knowing if the battery is more massive than the iPad 2's. A lot of battery "tech" is in the electrochemistry, and if there isn't a significant difference in mass between the old battery and the new one, then Apple's gone to a more advanced LiIon chemistry.

Each separate cell lists its rating of 3.78 volts and 14.60 watt-hour. They're graced with some more matrix barcode tags and wonderful inscriptions that read 741-0065-A P11GG9-01-F01TS. Swoon.

Chris Foresman at Ars Technica compared the energy density to the battery in the iPad 2, and it comes out about the same—around 0.0014 watt-hour / mm^3.

Apple physically increased the size of each cell by about 70%, explaining the big jump from 25 to 42 watt-hours.

Apple claims the new iPad is environmentally friendly with a "Recyclable aluminum and glass enclosure." The materials may be recyclable, but the assembled unit is not. We spoke yesterday with Steve Skurnac, president of SIMS Recycling Solutions—one of the largest electronics recyclers in the world. He told us, "Sealed units make it difficult to remove the batteries. From a recycler's point of view, the hazardous components [like batteries] need to be easily separated or removed."

Where is the WiFi antenna located? (In Apple's iPad announcement, there was a picture of the various wireless technologies which indicated that the WiFi antenna would be in the lower third of the iPad, and not behind the Apple logo.)

The revised three-cell design appears to be just slightly larger than the battery in the iPad 2—each measures about 125 x 65 x 4 mm, according to iFixit CEO Kyle Wiens. The cells in the iPad 2 measure 108 x 63 x 2.7mm, so the iPad 3 battery is actually about 70 percent larger.

The spectra used for LTE by Apple are currently consumed by SD-TV (700Mhz) or 3G (2100MHz) and not scheduled to be handed back for another 1-3 years which is why local carriers have had to use 1800MHz for LTE which is less popular (but hardly unique) than those other 2 spectra. Still, our 3G peaks at around 21Mbps which is good enough for virtually any use so it isn't a big deal. Apple chooses not to support 1800MHz since it is less popular than the other frequencies and they don't tend to localise devices.

What is the "pixel density" of the "Digitizer"? By that I mean, if I am creating a "notepad" type application using a fine-tip touch-panel pen, what kind of granurality (or clarify) am I going to draw on the LCD panel? Is the digitizer the same density as the display pixel density? I hope so!!

what is the digitizer pixel density? If I want to use a "notepad" type application, what clarity am I going to get on a line I draw with a touch-panel pen? drawing, network diagrams etc would be great on this iPad if its digitizer density matches its display pixel density.
